Abstract

Data is transmitted and received in a TDMA frequency hopping system by allocating two or more time slots for transmitting identical data packets, and transmitting the identical data packets in the allocated time slots at different frequencies. This requires the transmission of redundant information but reduces the likelihood of data loss. An adaptive scheme may be employed wherein more time slots are allocated for the repeated data transmissions in areas of poor reception while fewer time slots are allocated for the repeated data transmissions in areas of higher quality reception or when higher bandwidth is required.
